just loaded the trifecta tune into my colorado. Everything went smooth.
so how does it transform the truck? It's amazing...just night and day better than stock. You immediately feel the extra low end power. This is where this tune is providing the extra power. The truck no longer struggles to accelerate. Throttle response is great. It feels like i'm driving my 6.2 silverado. Just amazed how much more torque is available. It's totally worth every penny. I have 6k miles on my truck now. Wish i had this tune 5999 miles ago. I'll keep everyone posted as i get more time in the saddle!
thanks for the kind words and positive review!
how does one get a free demo?
i saw in the trifecta thread (from 12/2014) that they could send you a demo tune if you email them and ask.
with the trifecta calibration for the my2015+ chevrolet colorado and the my2015+ gmc canyon the sluggish off idle power, response, and drivability are areas that we have specifically addressed and have improved vastly over stock; if you look at the dyno graph in the link below, one of the key areas we pick up power on is between just off idle to about 2500 rpm. Low end torque and throttle response are both vastly improved with just the calibration installed; and we're currently offering demo/trial calibrations! (just email us for a free to try calibration, see link below for details)
we also include speedometer recalibrations as a service for users whom have installed lift kits and larger tires; the transmission shift points and even the power envelope is tire size and mass specific in the trifecta calibration for the my2015+ chevrolet colorado and the my2015+ gmc canyon: Individualization per vehicle (custom tuning) is available! (we can also adjust the shift points so that rpm/gear scaling is correct.)
would you like a demo trifecta calibration (trifecta try before you buy, speed limited to xx mph) for your my2015 chevrolet colorado or my2015 gmc canyon? (the demo calibrations include all of the trifecta advantage calibration features with the exception of being speed limited)
we offer demo chevrolet colorado my2015+ and gmc canyon my2015+ calibrations that are free to try because of our confidence in our product development and refined drivability. If anyone wants to try out our calibrations just send us an email and we're happy to dispatch a demo cal!
If you're interested, please email trifecta customer support and mention this offer!
i installed the tune also, i'd be curious to hear if you're having any lower speed issues? On mine, when i slow down to a stop, the transmission sort of jerks the truck, like if a torque converter was locked and let go. Let me know what yours does. I'll be sending logs to wot-tuning to capture the behavior, otherwise it's been a good tune, haven't noticed a big jump in eco mode yet for mpgs.

I did feel something off in the normal tune mode wen at slow speeds as well for the first 2 weeks or so of having it. Its gotten a bit better recently. I for sure think they need to make some transmission adjustments at the lower speeds. I told them about it this morning and i'm glad that i'm not the only one who's noticing it. They'll be able to dial it in more as long as people keep capturing it and sending the logs to them.
Also try driving with the cruise control set on a speed. Thats when i get the biggest mpg increases. 60/65 and lower is where i'm seeing the best improvement. I have a 10 mile trip from my house to work, during that stretch there only 2 lights and the speed limit ranges from 40-50. This allows me to set the cruise and i get 26-28 mpg consistently.
Its a good sign that there only seems to be this one flaw with the lower speed shifting, i think it should be fairly easy to correct. I'm also interested/excited for more owners to start using the tune and giving more feedback to wot-tuning to try and improve on an already good tune
chuck, thanks for the reply, was hoping i wasn't the only one having low speed issues, and what you described is exactly what is happening to me. I'll try capturing tomorrow and sending in logs, good that they're hearing it from more than one person.
hello jimogeek (and chuckvanstinkle),
we are working to replicate the described event on our development platforms: If successfully replicated an incremental update will be issued to address this immediately.
However, what i can tell you is that this event does not occur on all vehicles: A datalog of the event will help us to narrow down the vehicle conditions that this is occurring on; out of our development platforms that we started with, low speed drivability is a specific focus and the transmission shifts consistently smooth. Based on the limited reports so far, it may be possible that this condition only exists on a small percentage/minority of vehicles and at that with varying severity depending on vehicle. (jimogeek and chuckvanstinkle, you guys may be describing something different from one another)
this is not to say that there is not a problem, but its one that we did not come across previously: Please accept our apologies for the less than perfect experience while we are working to address and improve the exact conditionset/event.

No adjusting, making a guess, sending back, reloading, testing, sending backing, adjusting again.
the primary area of concern when addressing a street tune or tuner is: Not all tunes are created equal. What is delivered will depend on the circumstances of when the vehicle was tuned and the proficiency of the tuner.
For example, with the "street tune" process that you're describing, what if you discover something that you don't like after you drive away from the tuner? Would your tuner charge for a retune?:
With a trifecta calibration, when compared against a street tune or tuner or "artisan tuner", with a developed and validated calibration we have the following advantages:
1. We do our r&d on our own vehicles: With an "artisan tuner" the learning process is completed on your vehicle, and without any longevity testing or the ability to reproduce the issues reported on a development platform vehicle, depending on the work done troubleshooting anything will require you to bring the vehicle back to the tuner; the process will be more difficult especially if the operating conditions are different between where the tuner is located vs where you are located. For example, a cold start issue or something that you only experience while doing something very specific, etc.
Also previous experience with tuning a bunch of vehicles does not directly translate to proficiency and perfection on a particular vehicle especially if the "artisan tuner" does not have their own vehicle themselves to complete development and testing with.
This is not to say that all artisan tuners are bad however, for example, if you own a corvette c6 and have altered the hardware (aftermarket mods) extensively, such as a heads/cam package, aftermarket fuel injectors, and lets say a turbo kit on top of that, an artisan tuner will still be the most expedient method to at least get the vehicle driving. We have a substantial number of partner shops that use our calibration software/tools to facilitate a thriving ecosystem; however we are their preference for tuning tools not only because we have the most complete software suite and table support out there, but specifically because we provide our validation data and divergent environmental calculation models based on our own validation process for those vehicle types that we are their first preference.
To clarify, our distinguishing qualities are not just that we support things that others do not, but instead our best distinguishing quality is that we have the validation (testing) data to go along with our first to market vehicle support.
2. The data sample collected: With multiple in house development platforms for any vehicle type, we do our own development, validation, and testing on our own vehicles. For example, we test and develop based on our testing across all plausible environments, such as elevation, different climates, and then what happens if you have adverse fuel, etc. With an "artisan tuner", this process is limited usually to the brief period of time that the artisan tuner would spend with the vehicle: This process in my opinion is inherently flawed because if developing a correct tune on your vehicle takes two weeks, what are you going to do? Leave your vehicle with the artisan tuner for two weeks?
With any trifecta calibration and/or trifecta powerkit solution, what you are getting is the accumulation of thousands of hours of development time and testing across divergent environments. So your trifecta calibrated my2015 chevrolet colorado or my2015 gmc canyon will perform consistently, reliably, and consistently reliably no matter where you're at. We develop, test, and then validate thoroughly at all plausible environments, be it the mountains of colorado or a sunny florida beach, so that vehicle reliability will be as good as or exceed stock specifications and requirements.
This data also applies to the entire power envelope and hardware power tolerances: For example, what happens if you apply greater power to the transmission in a cadillac ats lfx (same engine and similar transmission to the my2015 chevrolet colorado 3.6 v6 lfx / my2015 gmc canyon 3.6 v6 lfx)? Lets double the power output and then find out!
3. With any trifecta calibration we provide the functionality to return the vehicle to stock at any time without incrementing the ecm write counter or increment entries in the flash history. The choice to either have your vehicle stock or calibrated is a choice (with the trifecta calibration series) that you can make at home without the limitation that you'd have to take it to your tuner to effect.
this again does not apply to your extensively modified corvette c6 because returning the hardware to stock will be far more difficult than spending the 15 minutes to return your vehicle completely to stock with a trifecta calibration.
the trifecta powertrain recalibration for the my2015 chevrolet colorado 3.6 lfx and the my2015 gmc canyon 3.6 lfx is also undetectable by any current or known gm diagnostic tools (does not increment write counter, and does not increment flash history entries, matches all cvn, checksums, and file hashes in the e92 ecm; retroactive flash history entry deletion for our partners/affiliates/friends/etc).
We provide this functionality as so that our customers will not be wronged by an aggressive dealership during a dealership visit. Besides dealership visits what if you wanted to effect a specific individualization or if you're trading in the vehicle for something else? To not have the ability to return the vehicle back to stock whenever you want is in my opinion is a pretty serious limitation and affects the freedom to do quite a few things with your truck for example.
4. Gm periodically issues calibration updates to address bugfixes, erratum, and/or to add new features or to effect vehicle recalls. A street tune will be tuned for when the artisan tuner last accessed the vehicle; our policy is to issue incremental updates corresponding with new gm calibration files, usually concurrently.
For any hardware based tsb's and/or part recalls, if you need to take a completely stock truck back to your local dealership, just flash your vehicle back to stock: Your truck is still dealership friendly.

the my2015 chevrolet colorado 3.6 v6 lfx and the my2015 gmc canyon 3.6 v6 lfx do not share the same ecm as the my2012+ chevrolet camaro 3.6 v6 lfx.
The my2015 chevrolet colorado 3.6 v6 lfx and the my2015 gmc canyon 3.6 v6 lfx use the e92 controller.
